Trivia

During the tutorial with Flowey, dodging his "friendliness pellets" causes the track to slow down in 5% increments. After the third time, the track slows down and stops.

During and after an encounter that displays the message "But nobody came", when all the monsters in a region have been killed, a slow and distorted version of this song's fifth and sixth bars play.[1] This slowed down version is known as "mus_toomuch.ogg".
